GRINDING-MILL.

Specification of Letters Patent No. 27,102, dated February 14, 1860.

and gearing portable grinding mills, so that the cylinders of the said mills turn in opposite directions (making the said mills double acting) and also-that, by the same peculiar mode of making, framing and gear ingthe cylinders or body of the said mills, may be adjusted, and set to stand and grind at any desirable angle, or plane, that is to say-that the barrel or body of the said mills, may be set to grind in a vertical position, or-in a horizontal position, or-at any intermediate angle between a vertical, and horizontal plane; and thus-the said mills-- in consequence of the double action of the cylinders, by turning in opposite directions, have a double force and power in grinding; and, in being adjustable toand from a vertical, or horizontal position, oradjusted, and set, to run, and grind, at any intermediate angle between a vertical, or horizontal plane-the said mills have, in this way, a very decided advantage over other mills whose barrels are stationary; inasmuch-as, by being thus adjustablethey may be made to grind more or less quickly or finer, or coarser, accordingly as the body of the said mills are set to run, and grind, in a more or less vertical, or horizontal position, as-it will be obvious-that the more vertical the body of the said mill is set runs, and grinds the more quickly the grain, or other substances being ground will pass through between the grinding surfaces of the said mills, and-consequently, the coarser the said substances will be ground; and, vice versa-the more horizontal the body of the said mill is set, to run, and grindthe more slowly-and the finer ground-will, the substances (ground) pass through the body of the said mills: And thus, as aforesaid-my improved grinding mills, possess important advantages over other, and ordinarily constructed portable grinding mills.

To enable others skilled in the art to make and use my invention, I will proceed more fully to describe and explain the constructlon and operation of my improved (double acting, and adjustable) portable grinding mills, reference being made to the accompanying drawings, and the figures and letters marked thereon, and forming a part of this specification: Figure 1, be ng a perspective .view of one of my said mills,- showing the body M, (the cylinders A, and B), set in the band G, and secured by the bolts J, to the inside frame; F, which is loosely set in the outside frame ODStjlIldlIdS S, S, in which it is held, so as to freely turn from a vertical, to a horizontal position, and vice versa,the shaft 2, of the large cogwheel C andthe opinion K, on the opposite side, forming the axis on which the said frame F, with the band G, holding the said mill, turns, andby which it is supported and hung between the standards S, S, as aforesaid: The said Fig. 1, also shows the mode of gearing the said mills, by means of the cog-wheels C C and G which operate in connection with each other, and in combination with the cylinders (A, and B,) which constitute the body M, of the said mills,-one of the said cog-wheels C being set on the shaft U of the inside cylinder A, (see Fig. 2,) an -another cog-wheel C being attached to (or formed with) the outside cylinder B, (which represents the body M, of the said mills), andthe other and larger cog-wheel C is set in the frame F, on the shaft 2, which, passing from the outside, through the standard S, and frame F, is stepped, rests, and turns loosely, in the strong band G, to which the bod M, of the said mill is secured, as aforesai ,-the said cog-wheel C thus set on the said shaft Z, at an equal distance between the other two cogwheels C and C formed or set on then respective cylinders A, and B, as aforesaidthe said large cog-wheel C when thus set, and is turned, by the crank L, or its equivalent, it operates in connection with the said cog-wheels C and C and consequently, through them, upon their respective cylinders A, and B, upon which they (the cogwheels C and C are formed, or to which they are firmly attached, so, as thus to turn the said cylinders A, and B, of the said mill, in contrary and opposite directions; and thus acting, it will be obvious-that the said cylinders A, and B, are turned by the said A cog-wheels (C C G with great force and power, and-with great velocity.

Fig. 2, plainly shows the peculiar mode of gearing the said improved mills (Fig. 1,) and, this figure (Fig. 2,) taken in connection with Fig. 1, will clearly illustrate the character, and principle of my invention. My said improved grinding mills (Figs. 1, and 2,) are made adjustable as aforesaid, by being hung in the standardss, s, (which may be considered as' the outside frame of the mill) so as to rest and turn freely on the shafts z, and pinion'K, or its equivalent. It will be obvious without illustration, that from the nature of this invention, or mode of con'structionthat by duplicating the said large cog-wheel G and, the shaft .2, and crank L, andsetting the same on the opposite side of the said millfrom that of .the present i'argeicog-wheel 0 the" same Would constitute, when set, a double gearin for the said mill, so as that by thus double gearing the said" mill, in this way, it

could be made to act with a double amount of force, and power, in grinding. It will be obvious without further illustration, that the body M, of the said mill (Fig. 1,) being set in frame (F,) and secured therein by the bolts to the band G, which surrounds the said body M-,and"by which it is hung in the said frame F, which hangs by the shaft 2, and pinion K, inthe standards 8, s, substantially as af0resaidthe said body M, may, by 'any' suitable means, be turned and set, to run, and grind in any desirable position vertical, horizontal, or oblique, so as to grind faster, or slower, or coarser, or finer, as the circumstances' of the case may require in grinding different kinds of grain, feed, or

other substances, which it maybe desirable to grind in the said mill.

In the construction of my said grinding mills (Fig. 1,) I do not confine myself to any definite shape, or size, of mill, nor-to any definite kind of dress, or grinding surfaces for the cylinders (A, and 13,) butin all matters relating to the said mills, except what is herein set forth as my invention,

(the makingframing, and gearing the said mills (Fig. 1,) substantially as herein de scribed), I make like as other mills, or as circumstances require,

Having now distinctly set forth the nature and object of my invention; as alsothe construction andoperation of 'my improved portable'grinding millsI desire to secure by Letters Patent, of the United States, what I herein claim as my invention, to wit:

1. I claim, in the construction of portable grinding'mills, the cog-wheels 0 0 and 0 when constructed, set, and operating in connection with each other, and the cylinders A, and B, of the said mills, substantially as herein described, and for the purposes set and for the purposes set forth.
